Three point charges lie along a straight line as shown in the figure below, where q1 6.06 uc, q2 1.53 uc, and q3-1.9 pc. the separation distances are d: -3.00 cm and d2 2.00 cm. calculate the magnitude and direction of the net electric force on each of the charges. ds (a) q magnitude direction select (b) 42 magnitude direction select (c) q n magnitude direction

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.

Acommercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -35°c by rejecting waste heat to cooling water that enters the condenser at 18°c at a rate of 0.25 kg/s and leaves at 26°c. the refrigerant enters the condenser at 1.2 mpa and 50°c. if the compressor consumes 3.3 kw of power, determine (a) the mass flow rate of the refrigerant, (b) the refrigeration load, (c) the cop, and (d) the minimum power input to the compressor for the same refrigeration load.

You throw a baseball directly upward at time =0 at an initial speed of 14.9 m/s. what is the maximum height the ball reaches above where it leaves your hand? ignore air resistance and take =9.80 m/s2.
